Nuvi 660 won't read my SanDisk 2gb card

Are you loading your POI files on the card via POI loader...?

Nick Jr;

Thanks for your speedy reply but I'm not sure I made myself clear. I am not working with POI files. I'm trying to see jpeg and mp3 files; pictures and songs. I did download software for the POI Loader software and tried to use it, but it seems like it's designed to work with .csv extension. I don't think that it's of any help with music and picture files. Any other ideas that I might try?

I have not personally run into this type of problem but someone has told me that since the 2 gb memory cards came out (for whatever brand or format), they don't necessarily work on all devices properly. This implies that they may easily work on your other electronic devices but not on some.
When I bought a cell phone with an mp3 capability a few months ago the tech person told me not to use a memory card over 1 gb because it may or may not work.
I hope this is not what's causing your problem.

You might make sure that you've created (on the card) the folders garmin, mp3, and jpeg.
Then I just drag and drop my mp3/jpg files into the appropriate folder using windows explorer and they show up when I browse in the mp3 player or look in the picture viewer on my nuvi 660.

Have you upgraded to the newest firmware for the 660. I believe I saw one of the upgrades that dealt with SD card size.

My Nuvi 660 came with the Fodors Travel Guide on an SD card. If your unit came with this card, you can test whether the card reader on the unit is working. As for MPEG music and JPEG files, I found it much easier to connect the Nuvi via USB and simply copy these files from my PC or MAC to the Nuvi as if it were an external hard drive.
